Temperature has stabilized after determinate time?

Where did you put the chart?

It's the item with the label "no label!". In your VI you deleted the label of that chart/graph, which is a no-go in my opinion…

Can you post your labview code?

I uploaded a snippet (read up that term in the LabVIEW help).

But I have/had problems when downloading the snippet as documented here. When you have the same problem please add a message in that thread…

Thanks. I'd try it if I used Firefox

I think I'll post it as an idea in the forum feedback forum. [EDIT I Bumped that post.] This should be standard.

I had a look on that new VI:

• The DAQAssistent is set to acquire 8 signals. The SplitSignal ExpressVI is set to split into 7 signals, but then you only use 6 of them. What's the reason for that decision?
• Now there is a string indicator with a missing label…
• Why is there an additional wire at the FromDDT function for "Temp Mancal LA"/"LA" indidcator?
• Why did you use a non-empty array constant to initialize the shift register holding the timestamp array?
• The same applies for the array costant/shift register holding the measurement data…
• Why do you want to build a 2D array from that 2-element array in the shift register and the 6-element array build from your measurement data?

Hi GerdW

• The DAQAssistent is set to acquire 8 signals. The SplitSignal ExpressVI is set to split into 7 signals, but then you only use 6 of them. What's the reason for that decision? fixed
• Now there is a string indicator with a missing label… fixed
• Why is there an additional wire at the FromDDT function for "Temp Mancal LA"/"LA" indidcator? fixed
• Why did you use a non-empty array constant to initialize the shift register holding the timestamp array? fixed
• The same applies for the array costant/shift register holding the measurement data… I thought I did as per your check1.png
• Why do you want to build a 2D array from that 2-element array in the shift register and the 6-element array build from your measurement data? fixed

Regards.

Can you post the the code you made?

Both are not fixed: the array constants used to initialize the shift registers still contain data/elements!

I cannot attach any code, I deleted the VIs after posting…

HI GerdW,

Here is my code, feel free to edit as necessary, and please post back.
Thank you very much in advance.

Hi aaswil,

it's getting better… 🙂

See this:

• Your DAQAssistent is set to read 200 samples at a samplerate of 200S/s: this will need exactly 1s. Why do you need an additional wait of 100ms in your loop?
• Why did you place that 100ms wait twice in your VI?
• Do you really want to read "finite samples" - or do you intend to use "continuous samples" in the DAQAssistent? Using a loop suggest you want to read samples continuously…
• Do you really need to read Pt100 sensors this fast? Does your DAQ device even support such sample rates? (Which hardware do you use?)
• No need for case structure, where only one case is called. No need for duplicate GetDateTime nodes in the loop…

Hi GerdW, 

I'm amazed at how clean your codes are.

• Your DAQAssistent is set to read 200 samples at a samplerate of 200S/s: this will need exactly 1s. Why do you need an additional wait of 100ms in your loop? Fixed
• Why did you place that 100ms wait twice in your VI? Fixed
• Do you really want to read "finite samples" - or do you intend to use "continuous samples" in the DAQAssistent? Using a loop suggest you want to read samples continuously… Continuously
• Do you really need to read Pt100 sensors this fast? Does your DAQ device even support such sample rates? (Which hardware do you use?) Daq 9216
• No need for case structure, where only one case is called. No need for duplicate GetDateTime nodes in the loop… Ok thanks, The initial idea was that if the user wanted the measurement time to be shown after starting the measurements

I still don't understand how the DAQ 9216 data will be represented graphically.
